Smartthings hub work with Samsung TVs older than 2016

I bought a Samsung Curve in 2015, it is a smart tv, I would like to use it with my smart hub to turn it on, off and set the sleep timer. Changing channels would be awesome and especially be able to do have go to the web browser on the TV and be able to make verbal searches and then surf the internet. Is there a device I can purchase to make the TV do these things?
